NOVA CYGNI 1992
B. Skiff, Lowell Observatory, reports that the field surrounding
Nova Cyg 1992 is not crowded with stars, and that there is only one
potential candidate for the nova's precursor readily visible on the
Palomar Sky Survey prints.  This candidate appears at mag about 18
on the blue print and about 17 on the red print.  The average of
the measurements of both prints yields the following position for
equinox J2000.0 (epoch 1952 July 31.4 UT):  R.A. = 20h30m31s.58,
Decl. = +52 37'53".4; the corresponding B1950.0 position is R.A. =
20h29m07s.03, Decl. = +52 27'44".0.
